SPECIFICATION forming part of Letters Patent No. 419,514, dated. January14, 1890.

' Application filed May 15, 1889. Serial No. 310,821. (No model.)

To all whom it may concern: 1

Be it known that I, GEPHAs GILBERT, a citizen of the United States,residing at Branford, in the county of Suwanee and State of Florida,have invented a new and useful Cotton-Gin, of which the following is aspecification.

This invention relates to cotton-gins; and it has for its object toprovide cotton-gins, especially of that class which are used forlong-staple cotton, with an improved feeding device, which shall beSimple in construction, durable, and effective in operation.

\Vith these ends in view the invention consists in the improvedconstruction and arrangement of parts, which will be hereinafter fullydescribed, and particularly pointed out in the claim.

In the drawings, Figure 1 is a perspective view of a cotton-gin to whichmy improvement has been applied. Fig. 2 is a top view of the same. Fig.3 is a rear View. Fig. 4 is a longitudinal vertical sectional view.

The same letters refer to the same parts in all the figures.

A designates the frame of the gin, which is provided with the hopper B,cylinder 0, and which is provided at its lower rear end with thecrank-shaft D, having pulleys E and F, which are respectively loose andfixed upon the said shaft. and through the medium of which latter motionmay be transmitted to the operating mechanism of the gin from anysuitable operating machinery. One end of the crank-shaft D is providedwith a drum or band-wheel G, from which a belt or band H passes over adrum I, mounted securely upon one end of a shaft J of the cylinder 0.The opposite end of the said shaft is provided with a cam-wheel K.

The lower end or discharge-opening of the hopper is provided with thedownwardly-extending fingers L L, in front of which works thevertically-reciprocating plate M, which is mounted upon arms N, attachedto a rockshaft 0, which is mounted in suitable bearings in the sides ofthe frame. The plate M is provided on its rear side with staples P, inwhich are secured the upper ends of pitmen Q, the lower ends of whichare mounted upon the cranks R R of the shaft D.

Mounted pivotally upon the upper side of the inclined feed board orhopper D are a series of downwardly=extending arms S S, which may extendslightly beyond the fingers L at the lower edge of the hopper-0rfeedboard, and which are provided with flattened central portions T,which are perforated to receive the bolts U, by means of which the saidarms are connected pivotally with a transverse rod or bar V, the ends ofwhich extend through openings WV in the sides of the frame. One side ofthe frame .is provided with a laterally-extending bracket X, to which ispivoted a lever Y, one end of which is connected pivotally with thetransverse rod or bar V,.while the other end of said lever is providedwith a notch Z, that straddles the rim or periphery of the camwheel K.It will be observed that when the latter rotates a vibrating motion isimparted to the lever Y, which in turn serves to reciprocate the rod orbar V transversely, thereby causing an oscillating or vibrating motionto be imparted to the arms S S, which in this manner are caused to feedthe contents of the hopper evenly and gradually out through thedischarge-opening.

The construction of this device is, as will be seen, exceedingly simple,and it is capable of being applied to cotton-gins of ordinaryconstruction without materially altering the same.

Having thus described my invention, I claim- I In a cotton-gin, thecombination of the intransverse crank-shaft, pitmen connecting.

the cranks of the latter with the vertical plate, vibratory arms securedpivotally upon the feed-board, a transverse bar connected pivotally withsaid vibratory arms, alever connected pivotally with said bar and havinga bifurcated end, the gin-roll, a belt connecting a pulley on one end ofthe shaft of the latter with a pulley on one end of the crankshaft, anda cam-wheel mounted on the other end of the gin-roll shaft and engagingthe bifurcated lever, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

CEPI-IAS GILBERT.
